Specification forming part `of Letters PatentNO. 16.260,"dated February 7, 1865.

oall whom, it may-concern: Be it known that I, JONATHAN E. MORSE, of Boston, in the county ofSuifolk, inthe State of Massachusetts, have invented certain new and useful Improvements in Evaporators; and I do hereby declare that -the following, taken y in connection with the drawings which accompany vandiorm part of this specification, is a description of my inventionsucient to ena- ,y ble those skilled in the art to practice it. f

Of said drawings, Figure'l representsaplau of a train of evaporators and their appendages in which my invention is embodied. '2

is a vertical cross section ofthe san1e,taken on thelineww. (Seen in Fig. 1.) i Figs; 3 and4 are respectively side and front elevations of the rllhis invention relates to system ofopen vlevaporating-pans designed, chiefly, for use in;

expelling waterfroin saccharine liquids; and

it consists in a peculiar arrangement of the" furnaces and fines by which the heat of thev furnace-fires may be made .available under'the cvaporatois-orby which it may be concentrated upon but oueof tl1e1n, or by which itmaylbe made to pass off-without affecting the contents.

of any Qf the evaporators; also, inthe arrangement,substantially that shown and described,v by which Steam-jets are employed to causea current of air to pass over the s'urfaeeiof the liquid contained in the evaporators`and by such passage to absorb and carry offrapidly the watery matter. .h

rlhe system shown in the drawings consists of three pansonly, though. the number of these may be increased, if desirable. `Said pansor cvaporators are located upon such different 'levelsthat' ilud in the highest -one'may be drawn through each of the others in succession, suitable pipes, a, being-arranged for this purposeand provided with stop-v a-lves. From the lowest pan inthe series or train pipe leads from near the `bottom thereof for the. purpose o'f discharging thcthiekened 'iluid or sirup i-nto 'a cooler or crystallizer.

Suitable furnaces.. b c, are located, as show n.

out-side of or `beyond the eraporators d and-e, and from these furnaces lead iluesf f and g g;

which are respectively locatedbeneath the ei'aporatorsd and e. These iluesf and gig discharge theircontents,respectively, through -lvertipal'pipes h and i into ahorizontaltluc, j,

over which is another horizontal` flue, 7;, di,-

products will pass direetlyiut.

reetly above the ,highest eyaporatingi` pan, li A system of dampers is-arrange'd i to control the passage ofthe heatand smoke from the'furnacesjfollows.'

Between the furnaces and the finesff and`- the up'pcr surfaces'of the dues f and g', thenthe openings from'the'furnaces into the lower dues, ff and g', are closed, and the pioductsof combustionpass along the upper lines, f and g, in

contact with the bottoms of thepans d and e; ,but whether said' dampers prevent thepassage of theY products of combustionthrou'gh either- -of said 'upper or. lower iluesthesaid productspass olf therefrom through the pipes ih and; t, as stated, `for'in Fig. 2`rnaybe s'een thejcorn;` -mn1iication of the -four 'liguesA f f" and gg -at their rear end. In said Fig. 2,ther|e-\may be .seen two openings between the flues j and lc,-

and tw'o dainpers, m and n', so arrangedupo'n one rod that when poneofsaid-openings is closed the other must. be. open..l .When the.
